The Javan rhinoceros is widely considered the rarest mammal in the world. Flirting with extinction for decades, it is estimated that only forty of the beast remain on the island of Java in Indonesia and less than ten in southern Vietnam. Once the most widespread rhino species, poachers and human development have made life increasingly difficult for the small rhino. None exist in captivity.

The enigmatic creatures have eluded documentation, and this camera trap footage is a boon for conservationists. Separate cameras filmed two distinct adult and calf groups. This proves that the rhinos are mating and perhaps even increasing in numbers. According to National Geographic, the footage was shot at the western tip of Java – the most populated island in Indonesia. For rhinos, they sure are cute.
